Abstract:

The theory of evolution holds that existing life forms evolved from earlier life forms through genetic change and natural selection. For a genetic change to affect the form or function of an organism, it has to affect a protein: the shape and function of the protein, the amount of it present, the cells in which it is expressed, the stage in development at which it is expressed, and so on. Thus, proteins are a very reasonable level at which to consider evolution. In general, protein evolution tracks organismal evolution. Protein evolution is not always a simple matter of an enzyme accumulating amino acid differences. This chapter states a simple example using three organisms and an imaginary protein called evolutionase. The evolutionase amino acid sequences from organisms 1 and 2 differ by 30 amino acids. The evolutionase sequences from organisms 2 and 3 differ by 29 amino acids. The evolutionase sequences from organisms 1 and 3 differ by 13 amino acids. In the activity stated in this chapter, an amylase evolutionary tree is constructed.
